Title: Improvements in and relating to packaging machine
IPC: B65B9/02
Filed: 1934-11-28
Abstract: 441,315. Wrapping-machines; packages. SALFISBERG, L. L., 39, University Court, South Orange, New Jersey, U.S.A. Nov. 28, 1934, No. 34237. [Class 94 (i)] In machines for forming packages by feeding layers of sheet material in proximity to each other, depositing articles in spaced relationship between the sheets, and bonding the layers to enclose the articles, the bonding means include mutually engaging heating rollers each provided with article recesses surrounded by peripheral crimping areas. Webs 8, 9 of the cellulosic material are drawn from rolls 6, 7 over idle rollers 15, 16 and pass between rollers 17, 18 formed with pockets 19 adapted to register during the rotation of the rollers. The articles descend a shoot 47, Fig. 2, by gravity until the foremost is stopped by a spring 48. Upon the descent of a forked plunger 54, it pushes the spring aside and forces the tablet through an aperture 49. Simultaneously, the other portion of the plunger, by the engagement of a boss 59 with a projection 61 on a trap member 51, moves the trap aside and allows the third tablet from the left, Fig. 2, to fall. The plunger descends with the tablets and positions them between the sheets of cellulosic material so that they each register with two of the pockets 19 on the rollers 17, 18 about to be brought together. The plunger rises and the continued rotation of the rollers brings the sheets together with the articles confined in pockets between them. The rollers are heated by resistance elements so as to cause the sheets to adhere, the temperature being sufficient to cause oxidation resulting in a brittle, easily torn closure. The surfaces of the rollers are formed with complementary crimped areas resulting in the areas shown in Fig. 4, being united, separation lines A, B, C being left between the areas. Knives 90 on the rollers produce cuts 87 to facilitate separation. The united strip is removed from the rollers by strippers 21, and is severed into lengths by a knife 68.

Title: Improvements in or relating to synchronous telegraph or like system
IPC: H04L7/00
Filed: 1930-11-13
Abstract: 367,019. Synchronous movements. ELECTRICAL RESEARCH PRODUCTS, Inc., 195, Broadway, New York, U.S.A.- (Assignees of Knoop, W. A. ; 36, St. Paul Road, Hempstead, New York, U.S.A.) Nov. 13, 1930, No. 34239. Convention date, Dec. 4, 1929. [Class 40 (iii).] Impulses of alternately opposite polarities are produced in response to incoming signals, and are superimposed in rapid succession on a storage device 30, and the preponderance of an impulse of one polarity alters the frequency of an alternating current by which a synchronous device is driven or controlled. In response to each change in polarity of the incoming signals a relay 12 operates to one of its contacts M, S, and shortly afterwards a delayed action relay 13 operates to its corresponding contact M, S, while a distributer brush 18 has passed from one to another of adjacent segments 17. The alternate segments are interconnected in two groups to opposite poles of a battery 19. When the distributer is in synchronism equal amounts of positive and negative charge are successively applied to the high-capacity condenser 30 and neutralize each other. Otherwise a charge of the predominating polarity is superimposed on the normal current produced in an electromagnet 20 by a tuning-fork 15, as described in Specification 339,994, [Class 38 (ii), Electric currents, Converting &c.], to increase or decrease the average grid potential of a valve 21. This increases or decreases the output of valves 21, 23 and hence the amplitude and frequency of the fork, which controls a phonic motor 29 driving the distributer. According to modifications the correcting circuit 11 ends in the windings of two transformers with high-permeability cores, as described in Specification 312,338, [Class 40 (iii), Telegraphs, Electric], Fig. 4 (not shown), or in a relay of the unbiased, Figs. 6 and 7 (not shown), or biased polarized type, Fig. 8 (not shown). Specification 317,528, [Class 40 (iii), Telegraphs, Electric], also is referred to.

Title: Method and circuit for producing a signal representing a sequence of binary bits
IPC: G11B20/14
Filed: 1971-07-28
Abstract: 1361626 Encoding LICENTIA PATENTVERWALTUNGS GmbH 28 July 1971 [30 July 1970] 35531/71 Heading G4C In a system for representing a sequence of binary bits by changes in state of a signal, the gap between successive changes of state is of a first magnitude for successive similar bits and of a second magnitude for successive different bits. In for example Fig. 1d successive like and successive different bits are represented by changes of the state at every clock pulse and every second clock pulse respectively. Successive similar bits may be represented by changes of state at every other clock pulse, different bits being represented either by a change of state of successive pulses or midway between pulses (Fig. 1g, not shown).  The circuit of Fig. 2 delivers an output signal of the form of Fig. 1d at the output of bi-stable 11 in response to a binary input signal fed in to the left of shift register 5. Clock pulses T are fed via gate 3 (enabled when a monostable is in its non-operative position) to step the shift register 5 and, after a delay 6, prime AND gates 8, 9, which are further primed by a signal 14. Similar bits in the two rightmost positions of the shift register enable equivalent gate 15 so that AND gate 9 is enabled to switch via OR gate 10 bi-stable 11. Different bits result in AND gate 8 being enabled via inverter 16 to switch the bistable and also trigger the monostable 2 so that the next clock pulse is inhibited by gate 3 resulting in a time delay of one clock pulse before the shift register is stepped again and consequently before the bi-stable 11 is re-triggered. The output of the bi-stable is applied to a writing circuit by an amplifier 12 to record the signal on a magnetic medium. The circuitry of Fig. 2 may be modified to have a long gap when successive similar bits occur and a short gap when successive different bits occur by either replacing gate 15 by an antivalence gate or by connecting the monostable to the output of AND gate 9.
